Active clinical trials for "Fever"

Fever is one of the main reasons for outpatient consultations in sub-saharan Africa. Following the introduction of malaria RDTs, clinicians face a high number of malaria-negative patients for whom they do not have a clear diagnosis. Through clinical history and examination, acute fever patients are categorized into: acute respiratory infections, urinary tract infections and other focal infections, diarrheal fevers and undifferentiated fevers. The latter being patients where no focal source of infections can be found during the consultation visit. In this proposal, the investigators focus on these acute undifferentiated fevers in an outpatient clinic. These fevers have the challenge of few point-of-care tests (POCT) available for the clinicians to identify the etiology of fever and guide treatment in resource-limited countries. As a consequence, over-prescription of antibiotics has increased. In order to improve patient outcomes while supporting judicious use of antimicrobials, there is an urgent need to change the management of febrile patients in low-income countries. This can only be achieved by providing evidence-based clinical guidelines for the management of these acute febrile patients. To develop such guidelines, epidemiological data on etiologies of undifferentiated fever need to be generated. The investigators will evaluate pathogen infection (such as dengue, chikungunya and others) in 640 patients ≥ 2 years old with acute undifferentiated fever. To evaluate the existence of aspecific and subclinical infections and co-infections, the investigators will also test a subsample of 200 patients with ARI, UTI, diarrheal fever and malaria. The investigators expect to have as main results: proportions of each syndrome among fever patients, key pathogens associated with undifferentiated fever and their clinical presentation and demographic characteristics.

Febrile seizures(FS) are the most common neurological disorder in chilhood and are a great stress for parents due to their dramatic clinical appearance. Using HRC-test(test for determination of homozygously recessive characteristics in humans) we analyzed presence, distribution, and individual combination of 20 selected genetically controlled morpho-physiological traits among FS patients and control to determine a possible deviation in the homozygosity level and genetic loads in the group of affected children and whether there is a predisposition to the occurrence of FS.

Febrile neutropenia is a common complication in pediatric oncology patients. Standard of care requires admission of all patients for intravenous antibiotics until cultures are negative, patients are afebrile and there are signs of bone marrow recovery. This often results in prolonged hospital admissions with significant financial costs, decreased quality of life and potential secondary infections. More recent data suggests it may be possible to identify a "low risk" group that can be discharged prior to signs of bone marrow recovery. At this time, researchers have been unable to identify a model that is safe for early discharge across institutions.

Febrile neutropenia are microbiologically documented in only 30% of the cases, and almost exclusively by blood cultures. The reasons for this low documentation are likely multiple: (1) some of these fevers are of non-infectious origin. (2) The bacterial inoculum present in the blood may be low and consequently undetectable by conventional blood cultures. The primary objective of the study is to assess new blood culture procedures and technics, in order to improve the diagnostic yield of blood cultures during febrile neutropenic episodes.

Chikungunya virus (CHIKV) infection has become a threat to public health worldwide. Reunion Island, due to the 2005-2006 epidemic, has acquired unique expertise and remains at the forefront of global research on this disease. The idea of genetic determinism of the clinical expression of infectious diseases has been supported by many epidemiological arguments over the past fifty years. The identification of genetic variants, associated with a disease, often allows a better understanding of the molecular mechanisms involved with consequent significant benefits such as the development of specific biomarkers for new preventive (vaccination) and / or therapeutic (drug design) approaches. In the absence of well-documented hypotheses about the genes potentially involved in the occurrence or evolution of a disease, genome-wide association studies (GWAS), whole genome, of nucleotide polymorphisms (SNPs) and the principle of linkage disequilibrium, under the commonly accepted hypothesis that the expression of a common disease is based on a small number of alleles commonly found in the population (frequency of minor allele greater than 1-5%), have become a method of choice, free of hypothesis, to specify the part of heritability of a complex disease and to identify its genetic determinants. Several epidemiological arguments support a significant proportion of genetic determinism in the explanation of the evolutionary pattern of Chikungunya, whose proportion of chronic forms can reach 40-60% in population-based studies conducted in the two years following an epidemic: There are few risk factors associated with chronic forms and these appear to be unclear (age, comorbidities with several elements of the metabolic syndrome) or inconsistent (immune burden) in population studies; The incidence of severe or atypical forms is rare in the order of 1% of infections; In contrast to the acute phase (J1-J21) for which there seems to be a role of the viral load intensity and a consensual pro-inflammatory immune signature according to a recent meta-analysis]; The role of the intensity of the viral load in the pathogenesis of chronic arthralgia (> J90) and their immune signature remain to be determined, the latter being rather nonspecific, according to studies conducted in Reunion, Italy or Singapore. These elements justify the interest of a GWAS in the Chikungunya to identify new avenues and mechanistic hypotheses likely to explain the chronic arthralgia characteristic of the disease.

A cross-sectional study on acute undifferentiated fever and the utility of biomarkers in differentiating bacterial from viral infection among acute febrile patients in Gondar, northwest Ethiopia.

The combination of fever and auscultation of a heart murmur suggests the diagnosis of endocarditis. However, fever itself increases cardiac output and could therefore modify heart sounds. The aim of the FeMur study is to measure the modification of heart sounds during fever. Heart sounds of 15 hospitalized febrile patients with a heart murmur will be recorded using an electronic stethoscope before and after resolution of fever. The records will be analyzed using a computerized application in order to quantify the intensity of heart murmurs.

This is a prospective clinical validation study of a novel regulatory approved (CE-IVD) diagnostic assay called ImmunoXpert™ that will enroll 1222 pediatric patients. The study aims to externally validate the tool's diagnostic accuracy and estimate the potential improvement in health and economic outcomes following the usage of ImmunoXpert™. Additionally, statistical analysis will be performed to compare ImmunoXpert™ accuracy to current practice lab testing (e.g. WBC, CRP, and PCT) and clinical suspicion at time of requisition. Enrolled patients will be managed according to the current standard of care and per standard institutional procedures.

This research trial studies the shotgun sequencing of blood samples in diagnosing febrile neutropenia in patients with acute myeloid leukemia. Studying samples of blood from patients with acute myeloid leukemia in the laboratory may help identify pathogens and accurately diagnose infections such as febrile neutropenia.
